MACHINE FOR MAKING HOLLOW GLASSWARE.

Application led October 23, 1911.

been designed with particular reference for.

use in the'manufacture of very large glass bottles, jars, demijohns andcarboys having l capacities of fromfive to ten or fifteen gallons. A

In the manufacture of such large Ahollow glassware I have discoveredthat it is neces sary to have means for maintaining the opening in theupper end of the glass blank, which is produced by the plunger. With solarge a body of molten glass, when the plunger is withdrawn, the glasscollapses or runs together and destroys the opening which has been madeby the plunger and which is necessary to enable the article to bevblown.

Therefore, the chief feature of this invention consists of introducingair under pressure into the plunger opening as soon asthe plunger isWithdrawn. This air under pressure tends both to maintain the plunger Yopening and to chill the inner surface of the glass around saidopeningwithout enlarging the blank so that the form of the opening andthe upper part of the glass blank will be maintained thereafter whilethe blank isbeing lifted kover to the blowing machine and compressed airintroduced therein for blow-.

ing of the article. Y

There are other novel features of this invention which will beunderstood from the accompanying drawings and the following descriptionand claims.

In the drawings Figure 1 is a side-elevation off .the machine, partsbeing broken away. Fig. 2 is a rear elevation of the machine looking inthe'direction of the arrows 2-2 in Fig. 1.

The drawings herein show a platform 15 carried by wheels 16 and having astation.-

ary tubular stand 17 secured thereon which carries a mold table 18 sothat it is rotatable and a column 19 which extends up centrally abovethe table, the lower end of said column fitting in stand 17, althoughthat is not shown. The table v18 is turned by hand,

handles 2O being provided for that purpose. The directions of themovements of the table are indicated by the arrow in Fig. 1.'

In making large hollow glass ware the volume of glassis so large and hotthat a jar vof the mold, or table on which the mold is mounted, is very'liable to displace or misform the glass and interfere with the mak-- ingof the blank so that it can not beblow'ri, hence there is providedherein means for preventing such jarring of themold on the table 18.This is shown .in Fig. 10 where 'a notch 21 is made in the under side ofthe table and which is beveled on the sidein the direction which thetable moves. Into said notch a stop rod 22 enters, said-stoprod beingverticall)7 reciprocable in the adjustable guide bloc and a cross bar 24of the Af shaped e 25 secured .to the platform 15, see Figi-5 1: Aspring 26 tends to hold the rod upinto-av position to engage the notchin the table and willreturn said rod after be'- ing depressed by thepedal lever 28 ful crumed on the "pin29'fto the base. vrThe ad.1justable ginds-block 2B is' secured by two rods 80. which extend. inopposlte directions 'I in the top of the frame 25 so that the upperl4grooved t0 close about the sistsqf an arm secured column 19 at itsupper end and carrying the and loosel through the frame 25, and'` oneach rod t ere is a spring^32 lyingbetween the lframe 25"and the nut 33on the outer end of the rod.' This connection permits some lateralyielding of the stop rod 22 Aand said rod extends through a largeopening 34 a table. There is an annular series of these molds and uponthem lift-overs 37 ya're placed which may be formed in the usual way.The plunger mechanism herein shown conto the stationary plungehead 41through which the plunger 42 extends. There is a spring 43 aroundthephmger above the head 41 and below the collar 44 y'secured on theupper end 'of the plunger; There is also a cross bar 45 through whichthe plunger extends about midway and a spring 46 lies about the plungerbetween said bar and-the plunger-head 41. A collar 47 is secured to saidplunger below 'said bar 45. Rods 48 extend looselyr through the ends'ofbar .45 and on their lower ends carry a cross-bar 50 and springs 51surround the rods 48 and lie between bars 45 and 50.

" laterally from the arm 40, see

' The plunger is actuated by the hand lever 53, which is secured betweenitsends on a shaft 54 mounted in the sleeve 55 extending outer end ofthe lever 53 is counterbalanced by a weight 56. A pair of arms 57 aresecured to the-shaft 54 and lie, oneon each side ofy theA arm 40 and areconnected by the connecting rods 58 with arms 59 extending ,laterallyfrom the collar 44 on the upper end of the plunger. Hence when the lever53 is pulled downward it will depress the plunger and form the opening60 in the upper end of theglassblank6l, as shown in Fig. 3.v

The yielding stop 22 is located beneath the plunger, see Fig. 1, so thatit stops the table in the right position to bring the mold and lift-overunder the plunger.

After the blank has been pressed and the plunger elevated, the stop 22is depressed and the tablerevolved slightly and the pneumatic apparatusis swung over to the left and the blowhead 65 immediately brought downupon the lift-over and press mold carrying theA blank' just pressed andair under pressure is introduced therein to maintain'the opening 60 byits pressure and by chilling the glass somewhat.

Fig. 4. Thel The pneumatic apparatus is carried by laterally swingingarm 66, see Fig. 5, which,

moves from the full line position to the dotted line position thereshown, and back again, completing the operation of the machine. Thisarm, as Vshown in Fig. 6,l is mounted on the column 19 between collarsv67 and 68, which are secured to said'column 4and having bearing balls169 and located between'v the collar 67 and said arm 66. On its outerend it carries anair cylinder 78 which may be of the usual type in glassblowing machines and which contains a pis for actuating the piston rod69' thatcarries the pneumatic head 65.*which is connected through an airpassage, 'not' shown, from the cylinder of the ypneumatic head to theglass blank.

' Air-is supplied to the cylinder from the stationary pipe 70 lsecuredto the top of the column 19 and leading from a source of air underpressure and a flexible tube -71 leads from the pipe 70 to the valve box72, see 1 Fig. 5. Pipe 73 leads to the lower'end of the cvlinder andpipe 74 leads from the valve box to the upper end of the cylinder. Thepiston rod 69 is hollow and open within the cylinder on the upper sideof the piston in said cylinder and air `entering through the upper pipe74 depressies the pneumatic head and enters thecorrespondingblank whileair entering the pipe- 73 elevates the vpneumatic head. Thisconstruction is well known in glass blowingmachin'es. The valve in thevalve box 72 has an outwardly extending valve stem 80 with a spring 81vabout it for holding it normally in position to shut off the passage ofcompressed air through the valve box. The

valve stem is actuated by the engagement of the arm 82 on the valve stemwith a horizontal plate 83 while the valve vstern. 80 and arm 82 arebeing moved to the right, as 'shown in Figs. l and 8.

The plate 83 or track is a long bar, see' Figs. 4 and 5, concentric withcohunn l19 and extends throughout the extent of the lateral movement ofthe arm 66 carrying the Ipneumatic head 65.

arm 85 which at its inner end is secured to the collar portion of thelarm 40 where it surrounds the column 19 so that in effect Said track83is` supported, as shown in Fig. 2, by a fastened the arm 85 is securedto column 19. A ver- .tical bar 86 connects the outer endV of arm85'with a metal portion of track 83 andtwo inclined b ars 87 extend fromthe upper-end 'of bar 86 and are secured to the track 83 near its ends.Track 83, as shown in Figs. `7 and 8, is made of angle iron and ahorizontal. surface thereof has` at its left hand end a slot 187.

The arm 66 carrying the blowhead is swung from the dotted line positionshown n Fig. 5 to the-full line position by the for carryingand movingthe press mold, an

oscillatory arm above said table, pneumatic means carried by the outerend of said arm adapted to be moved down upon the press mold after theplunger has been removed and the table actuated .to move the press moldfrom beneath the plunger for introducing air into the opening of theglass blank, -said arm and pneumatic means b ing adapted to travel' withthe table and p ess mold.
